# Learn String Manipulation by Building a Cipher - Step 38

### Tell us what’s happening:

This is what I have done but it not correct

``````
/* User Editable Region */

text = 'Hello World'
shift = 3
alphabet = 'abcdefghijklmnopqrstuvwxyz'
encrypted_text = ''

for char in text.lower():
if char is empty space True otherwise False:
print(space!)
index = alphabet.find(char)
new_index = index + shift
encrypted_text += alphabet[new_index]
print('char:', char, 'encrypted text:', encrypted_text)

/* User Editable Region */

``````

You can try by simplifying your `if` statement like this: `if char == ' ':` .
`space` isn’t a reserved word in Python.

You need to really understand the concept of `if` statements, I suggest you read more about it and see some examples: https://www.geeksforgeeks.org/python-if-else/

``````if condition:
# Statements to execute if
# condition is true

if i > 15:
print("10 is less than 15")

if i == " ":
print("i is an empty space")
``````

`condition` is an expression which, when evaluated, will either be true or false. You don’t need to write true and false.

5 == 5 will evaluate to true
5 == 10 will be false

``````if 5==5:
print("this will print")

if 5 == 10:
print("This will not print")
``````

I hope this helps!

Hi,

``````text = 'Hello World'
shift = 3
alphabet = 'abcdefghijklmnopqrstuvwxyz'
encrypted_text = ''

for char in text.lower():
if (char == ' '):
print("space!")
index = alphabet.find(char)
new_index = index + shift
encrypted_text += alphabet[new_index]
print('char:', char, 'encrypted text:', encrypted_text)
``````

I struggled with the same issue but found the problem.
You shouldn’t use the paranthesis for if condition. below is the final answer

It is great that you solved the challenge, but instead of posting your full working solution, it is best to stay focused on answering the original poster’s question(s) and help guide them with hints and suggestions to solve their own issues with the challenge.

We are trying to cut back on the number of spoiler solutions found on the forum and instead focus on helping other campers with their questions and definitely not posting full working solutions.

Thanks, @MLearn !!
That worked for me, though not sure why we want the paranthesis removed.
